The response to this recycled Trump battle cry of essentially - Love it or leave it is simple.
Democrats/liberals/progressives/the squad all love their country and want good things for Americans. Criticism of the President/GOP/GOP supporters is not criticism of the country, it is a criticism of how it is governed. Dictators want people to believe that criticism of themselves/their policies/their rhetoric is the same thing as hating the country. That is unAmerican.
The First Amendment guarantees the right of all Americans to voice criticism of the government.
Granholm came close to this in a CNN interview, but missed the critical distinction between criticism of country and criticism of Trump. The words that Americans have the right to criticize their country (as opposed to the right to criticize the government) should never be uttered by a competent Democrat politician.
